I've found that with any FB groups having to do with old bikes, when someone asks a question there might be a good answer or two but they are buried under half-baked ideas, ridiculous attempts at solutions, newbies trying to answer things they have no idea about, misdirections, etc. We may not be able to like posts, but likes also don't screw up some algorithm that rewards people who don't know what they are talking about yet who post a ton. Don't get me wrong -- we have our fair share of cantankerous characters and there are some rude back-and-forths, but most of the info generally hits the spot.
